|

|
|

|
* |
|
41
|
|
|
|
|
|
|
* This differs from normal pthreads rwlocks in two ways: |
|
42
|
|
|
|
|
|
|
* 1. Separate APIs for releasing read locks and write locks (as |
|
43
|
|
|
|
|
|
|
* opposed to the pure POSIX API which only has one unlock fn) |
|
44
|
|
|
|
|
|
|
* 2. You should not use recursive read locks (i.e. grabbing a read |
|
45
|
|
|
|
|
|
|
* lock in a thread that already holds a read lock) because the |
|
46
|
|
|
|
|
|
|
* Windows implementation doesn't support it |
